ABSTRACT:
A drum for winding up filamentary material, such as optical fibers, has a generally cylindrical unitary flangeless hollow body of airtight and somewhat resilient polymeric material inflated under a fractional gauge pressure through a valve in one of its end walls. A bore in each end wall, centered on the cylinder axis, enables the drum to be coupled with a driving mechanism.
